摘要
目的了解北京市大兴区市售食品中食源性致病菌污染状况。方法 2006-2008年,采集大兴辖区内的10类食品,对沙门菌、大肠埃希菌O157:H7、金黄色葡萄球菌、单核细胞增生李斯特菌、空肠弯曲菌和副溶血性弧菌等6种食源性致病菌进行监测分析。结果食源性致病菌检出率为11.96%(67/560)。金黄色葡萄球菌的检出率最高(6.79%,38/560),其次为单核细胞增生李斯特菌(3.57%,20/560)和沙门菌(1.61%,9/560)。560份食品中均未检出大肠埃希菌O157:H7、空肠弯曲菌和副溶血性弧菌。生牛奶中金黄色葡萄球菌检出率最高(30.67%,23/75),其次为生肉(15.29%,39/255)、鲜冻水产品(5.45%,3/55)和熟肉制品(2.67%,2/75)。结论大兴区市售食品中食源性致病菌污染较为普遍,生牛奶、生肉类、鲜冻水产品及散装熟肉制品可能是导致食源性疾病的高危食品。
Objective To investigate the occurrence of foodborne pathogenic bacteria in retail foods in Daxing,Beijing.Method From 2006 to 2008,ten kinds of retail food samples were collected from Daxing and analyzed for the presence of Salmonella,Escherichia coli O157：H7,Staphylococcus aureus,Listeria monocytegenes,Campylobacter and Vibrio parahemolyticus.Results Of the 560 samples tested,67 （11.96%） were positive for foodborne pathogenic bacteria.A high prevalence of 30.67% （23 /75） was shown in raw milk,followed by 15.29% （39 /255） in meat products,5.45% （3 /55） in aquatic products and 2.67% （2 /75） in cooked meat.The positive rate for S.aureus was the highest （6.79%,38 /560）,followed by that for L.monocytogenes （3.57%,20 /560） and Salmonella （1.61%,9 /560）.None of E.coli O157：H7,Campylobacter and V.parahemolyticus were detected in any samples tested.Conclusion Foodborne pathogenic bacteria were frequently found in retail foods in Daxing.Raw milk,meat products,aquatic products and cooked meat were at higher risk to cause foodborne diseases.
